RECLAIMING ATTACHMENT FOR SGALPERS.

Application filed February 3, 1927. Serial No. 165,563.

My invention provides a simple and eliicient grain reclaiming attachment or device adapted for use in connection with scalpers and particularly designed for use in connec- 5 tion with scalpers of the type disclosed and claimed in Letters Patent ol the United States No. 1,568,267, issu edto Clarence VJ.

Carter as inventor of date January 5,1926. In the use of such scalpel-s, all large objects, such as sticks, pieces of paper, leaves, nails and other large foreign objects, will be carried out of the commingled grain and usually deposited directly on the in whichthe device is installed. In practice, it has been found that some good grain will be carried over with the tailings, and it has been noted that the chiefcause of this carrying over of the good grain is the presence of leaves, pieces of paper or other flatobjects in the commingledgrain. The amount of good grain that will be with the tai'lings is very with the total amount of thus carried over small as compared good grain passed through the scalpel", but in a machine of large capacity, the'amount of good grain carried over in the course of a day has been found to be well worth saving and, hence, it has been the practice in removing the same by hand and to lunch as possible of the grain.

vthe tailings to sift thereby reclaim as icarried-over good My invention provides an automatic reclaiming separator or device for reclaiming the good grain from the ta lings, and the preferred form panying drawings: reclaiming separator receive from a rotary scalper 01 the is illustrated in the accom- In these drawings, this shown'as vapplied to Carter type above identified, and which scalper is applied in connection with an aspirator,

For the present illustration, we will assume that the material to be separated is wheat, which contains some oats, small seeds and various other foreign objects, such as pieces of paper, leaves, nails, sticks, straws and the like, In the arrangement illustrated, this commingled stock y is assumed to be delivered "from the spent 5 into a hopper 6 from which the discharge is controlled by a gate 7. The stock discharged from the hopper :6 is delivered to a large-mesh rotary scalping screen 8 of cylindrical form secured to heads 9 carried by a shaft 10 journaled in suitable fixed bearings 11 on the sides of the machine. Clearly disclosed in the prior Carter patent above identified and as already indicated herein, the meshes or openings in the rotary scalping screen aremany times larger than sufiicient to pass freely therethrough all of the different grains such as wheat, oats, rye, barley and the like, which are to be separated from coarse materials such as StlCl S, I1L1lS, leaves,

pieces of paper and the like. he cylindrical scalping screeu Savorks in an open housing Secured to the heads 9 andlocated within thescreen 8 areoverlapped restraining 'bafile plates 15 that restrict the flow oftl e grain substantially as indicated in Fig. 1, when said screen 1s rotatedin a counter-clockwise direction in respect/to said View. Allof the large particles, such as sticks, nails, leaves, pieces of paper, straw and the like, will be carried over and discharged from the exterior of the screen 8 ion the front side of the machine, to witi at the left in respect to Fig.1.

The commingled stock cleared "of the tailings will beedel'ivered into a lower hopperlike housing 15 and from thence to a discharge spout 16: but on its way to the housing 15, such stock will be subjected to suction from an air blast produced an aspirator, which, in so far as it is shown, comprises a casing 17 and an air outlet tube 18, which latter may be assumed t be conneetedto the inlet of a suction or blower hopper-like housing has an end wall 15 which con nects with'the side wall of the catch trough 19 as shown in Fig. 1.

The tailings, which, as already noted. are carried over by the rotary screen 8, will be delivered to the reclaiming separator. This. device may be permanent or detachableiand is capable of modification but, as shown, comprises a catch trough 19 extended transversely of the machine just in "front of the screen 8 and in position to receive the tailings. This "trough, as shown in 1, is rigidly secured to the lower housing 15 through the medium of the wall 15 and it is provided with an imperforatc deck-like bottom 20 which, as

shown in Figs. .2, 3 andet. extends from the left-hand end of the trough and delivers into the upper-portion of a receptacle afforded by theupper end of a reclaiming spout 21. The

separatingbelt, preferably a perforated rubber belt 22 is arran ed to run. over ulle s 23 and 24tsecured, respectively to shatts23 and 245 journaled in suitable bearings on the extended sides of the trough 19. The upper [portion of this belt 22 runs on the deck-like botto1n20 of the trough and passes over the open upper portion of the reclaiming: trough 21. Theshat't 24 carries a ratchet-like cam 25 that operates on the free end of an arm 26 secured toa rock shaft 27 journaledhin thedepending sides of the trough 19and located in the receiving end of the spout 21. Ptigidly'se cured to this'shaft 27 is an approximately L- shaped belt-vibrator or arm 28, the transversev tree portion of which is positioned to strike against the under surface of the upper portion of the belt 22 at a point close to the lefthand side of the spout21,directions-being taken in respect to Fig 4.

A coiled spring 29, attached to the arm and adjustably anchored to the adjacent depending side of the spout 19, keeps the free end of thearm 26engaged with the cam 25 and causes the freeend of the ar1n28 to. strike the belt each time that lug otthe camj25 passes from under the free end of j said arni26. Secured to the inner plate of p the trough 19 and located. between the upper through thebelt ontothe inclined bottom of 1 the lower housing 15.

and lower runs of the belt 22 is an inclined plate 30 that directs the material passed Tn the machine shown, the rotary screen 8 i 1 is given its rotary motion, the belt 22 is given traveling motions, and the beltvibrator 28 is givenits oscillatory movement through the. following drivlng connections: The

;;power, is transmitted through a sprocket chain,-not shown, which runs over a sprocket 31 onthe shaft 10 of the rotating screen, and said shaft 1 0 is provided with another sprocket 32'. A sprocket chain 33 runs over the sprocket 32 and over a 'sprocket'34 on a short countershaft 35 journale d in suitable bearings 36, (see Fig. 3), secured to the adother grains. 1 i I 'tice.

j aeent side plate of the trough19. The sh aft 35 is provided with a bevel pinion 37 that lnesheswitli a bevel gear 38 on the pulley Following out the illustration of the cleaningof wheat, 1t is understood that the wheat comnnngled with more or less-oats,rye, barley, small seeds and dust, will pass through thescalper into the lower hopper 12, and on its way to the discharge spout 16 will be subjected'to an upward draft produced by sucassumed, of leaves, pieces of paper, sticks,

nails, straw and the llke, together with acom-- paratively small part of the good wheat and possibly some still smaller percentage of oats and other materials foreignto the wheat, will be delivered into the trough 19 and onto the perforated belt 22. Materials such as wheat will get into the perforations of the belt and i will be carried into the receivingend ofthe reclaiming spout 21.

To cause gram lodgedon the belt between the perforations to flow through the belt per=' forations and hence to pass-through the belt into the receiving spout, "the vibrator 28 1s caused to strike the belt with a rapidlyrrepea-ted series of taps at the place where the belt is exposed above the receiving end of the spout.

' Preferab ly,'the perforations in the belt are A large enough to receive andpa-ss therethrough wheat, oats, rye, barley and in fact all good grain, but not large enough to pass'therethrough the coarse or larger foreign'materials usually designated as vtailings. O-i

course the perforations maybe made of'any desired size as for example, of a size or shape that would pass therethrough only wheat but not oats, rye or barley. Obviously, there is no objection to returning to the main stream of grain all good gralnsuch as wheat,

oats, rye or barley inasmuch as, the main the wheat from the other grains.

A scalping screen continuously movable I in a definite direction and provided with openings much larger than required totreely pass therethroughall grains such as wheat, oats, barley and rye, whereby the body of commingled grain will pass freely through said scalping screen but large long objects such as straw, sticks, nails, leaves and pieces of paper will be carried over said scalping screen carrying therewith a small amount of good grain, in combination with a reclaiming screen receiving the materials carried over by said sca-lping screen and having openings through which the grain can pass but through which the foreign objects such as straw. sticks, n ails, leaves and pieces of paper cannot pass, whereby the grain is saved from the said coarse scalpings, and a grain receiving hopper common to said scalping screen and said reclaiming screen.

2. A rotary drum-like scalping screen mounted on an approximately horizontal axis continuously movable in a definite direction and provided with openings much larger than required to freely pass therethrough all grains such as wheat, oats, barley and rye, whereby the body of commingled grain will pass freely through said scalping screen but large long objects such as straw, sticks, nails, leaves and pieces of paper will be carried over said. scalping screen carrying therewith a small amount of good grain, in combination with. a trough arranged to receive the materials carried over by said scalping screen and provided with an imperforate deck-like bot tom, a perforated reclaiming belt movable over said deck and beyond the end of the same and operative to pass grain therethrough but to carry ofi the foreign materials such as straw, sticks, nails, leaves and pieces of paper, and a grain receiving hopper common to said scalping screen and reclaiming device.

In testimony whereof I affix my signature.
